DESIGN AND OPTIMIZATION OF FINS FOR HEAT TRANSFER ENHANCEMENT USING ANSYS

Abstract

One of the most important engine components that is subjected to extreme temperature changes and thermal strains is the engine cylinder. Fins are put on the cylinder's surface to increase the rate of convection heat transfer. The current study looks at how pin fins that are unique shaped (circular, conical draught pin fin) and fitted with cylindrical cross-sectional to increase the variation in the heat exchange rate may improve heat dissipation and pressure drop across a flat surface. Heat sinks are used in heat dissipation applications. Heat sinks that have been around for a long time are typically insufficient to keep newer, hotter working components cool. Blades, for example, have larger surfaces that aid in heat dissipation. Holes in the fins help speed up the rate of heat dissipation. Because it is exposed to high temperatures and heat stress, the engine chamber is a crucial component of the engine. The particles are dispersed around the cylinder surface to increase the quantity of convective heat exchange. When fuel is consumed in a motor, heat is produced. Friction between moving components is a common source of extra heat. Expanded surfaces called fins are put on the perimeter of motor cylinders in an air-cooled I.C engine to increase heat transmission. As a result, fin analysis is critical for improving heat transfer rates. The major goal of this research is to look at previous studies that looked at changing the shape and material of the cylinder fin in order to improve the cooling fine heat transfer rate. Temperature changes of fins created across four geometries (plate fins, circular pins, holes, and pipe fins) were assessed and authorized using ANSYS software, as well as a clear state heat exchange research. The trials were carried out to examine whether the fins had any temperature changes. Fine performance models are assessed in Ansys using experimentally produced heat flow and temperature changes, and FEM is utilized to identify temperature variations in various fine models in the field. The goal of this research is to enhance the rate of heat dissipation by using wind movement. The research's major goal is to increase thermal characteristics by modifying shape, material, and fine design.
